We asked our resident Site Services Engineer Matt Bullars, to give us an insight into an average day on site for our technicians.
Travel – Generally, sites request Macalloy technicians on site for 8AM. Although Macalloy are located central to the UK we must factor travel time into arriving on site. From Sheffield to Central London, this can take generally 3 hours as a minimum, which makes for a 5am start at the latest! Site operations are often long days.
Induction – You will not get onto any site within the UK without a safety induction. These of course vary in length depending on the current site works. These generally take about 30 minutes. However, the longest I have completed lasted 3 hours and involved a multiple-choice test to conclude.
Set Up – Moving the equipment to the operation area is hands down the worst part of the day. The equipment can vary significantly in size and weight. Imagine the enthusiasm you have from floor 1-10 to carry the kit, that soon drains when you realise you have another 15 stories to climb. Crane bases on high rise buildings are not anyone’s favourite, for obvious reasons.
Assessing Site – Ensuring the safety of technicians and surrounding workers is essential. Appropriate access and a clear safe working zone should be provided. If not, Macalloy technicians will not perform any works. Safety is always priority!
Communication – Often engineers and clients are interested in the tensioning operation so will show interest in the first cycle of stressing. Our team love to explain the process and share their experiences on other projects.
Stressing Cycles – Often, a pre-determined stressing cycle is provided to technicians prior to arrival. This gives them guidance on the order and specific loadings in each bar. The number of cycles is usually driven by the load distribution within the structure. A lot of designs now instruct for incremental loading e.g. 25%, 50%, 75% and 100% of load. Incremental loading is useful for reducing lock off losses.
Recording – Macalloy site technicians are always requested to complete stressing records. This aids in logging details of the operation and aids in compiling the stressing report. Macalloy keep a copy of this report and often customers request copies for their own records.
Sign Off – It is important that once all works are complete that the client is happy with the operations and results. Usually a copy of the original documents is shared for full traceability of the stressing.
